Hey community, I'm currently immersed in a project that involves integrating a diverse range of IoT devices, including smart sensors for environmental monitoring, RFID readers for inventory tracking, and actuators for remote control applications, into a unified system. While these devices...
Hi everyone,
I am working on an RFID reader using HTRC110 with a coil antenna of 18cmx12cm but I could not get the desired range (at least 10cm) for a small tag 10*12mm like this one Hitag S 256 Pigeon Ring. In this document HTRC110 Application note I found out that I can use external power...
So I'm doing a quick proof of concept demo for work that uses these RFID chips. I'd like to make more of the demo units but I am out of the sticker tag antennas I use and I can't get more in time.
I have the SL3S4021 model with two frontends. For my demo I want them to read from as far away as...
Hey Guys,
So I'm pretty much a total noob how radio frequencies work.
I stumbled on this forum and thought its a good place to ask this.
Is there a way to build a large-distance animal microchip scanner?
I was curious if there was a way to look for microchipped animals via scanning microchips in...
hello, I hope to make a simple rfid that can transmit 20 different frequencies and receiver that can decode those signal transmitted from rfid. I hope that rfid without any transistor so i can design it very small I don't need it long range. I hope max 10 meter range. please post your Idea
Greetings Everyone.
I am looking to develop a small educational project as an end of term project for my Graduate programme. The concept is to identify a moving object and then categorise it as either 'FRIENDLY' or 'ALIEN'.
The term 'FRIENDLY' means they will be known to the system and the...
Hi everyone,
Im trying to get an htrc110 to read an ID to my pic 32.
Ive already got all the pcb development done and now all I have to do is write the code.
Ive read the datasheet at least 4 times now and it doesn't supply any sort of examples to help out and the software library doesn't...
Hello everyone
I'm newbie to RFIDs and I would like make large area reader.
I found antenna from the Taobao site.
Which is 45x30cm coil antenna.
But the problem Is I can't seem to find reader that can use that large antenna.
Any suggestions or help will be appreciated.
Here is the antenna link...
Hello everyone

I'm working this circuit for a weeks.
But i can't seem to understand full details and it's working since i'm almost newbie to Radio Communications.
So i have few questions on this circuit.
1.Can anyone explain me deeply about this circuit?
2.Is it possible to change antenna...
I don't know where to ask but I was wondering if someone here has worked with it and could give some idea. Hope so.
A module ( MFRC522 ):
Schematic:
An MCU ( PIC18F452 ) is powered with 5V, module is powered from 5V(DC) -> 3.3V(DC) converter and all logic pins ( SS(SDA), SCK, MOSI, MISO...
I am trying to build an escape room puzzle, where someone holds a key fob up to a sensor and a maglock opens, and I went online to buy something that I assumed was ready-in-box but instead they sent me the photo attached which I'm 99% sure was originally a car immobilizer and is now being used...
Hey there, I wanna know how to write a code by Codevision for reading RF01D data...
I know I should use USART...that's all I know...
It's an ATmega 32 and RF01D
in first step what changes should I apply on Codewizard?
thanks
